To aZZ wkomz't may concern. I

Be it known that I, JAMES A.FnNTREss, a citizen of the United States, andvresident of Norfolk, in the county of Norfolk and State of Virginia,-'have*invented certain new and useful Improvementsl in Windows, of which the following is a specification.

My invention relates to improvements in windows of that type in which the sashes are mounted for both sliding and. swinging movements whereby they may be manipu# lated for convenience in cleaning and repairing the same or for other purposes.

More particularly it is a purpose of my invention to provide means whereby opening or closing movement of either sash will iinpart corresponding movement to the other sash, and in association with such an arrangement to provide other means of a sim ple and inexpensive nature which will eliminate the necessity of sash cords, pulleys and weights to retain the sashes in desired adjusted positions.

Another purpose of my invention is to provide an arrangement including a `screen section in each sash and to so dispose said screen sections relatively that when either sash is moved to an 'open position, its attached screen section will be brought into position to close a portion of the space previously occupied by the other sash.

A further purpose of my inventionis to provide a structure which is capable of accomplishing all of the foregoing and which may be associated with window framesof standard construction without material als terations thereto and with a minimum of y A sists of a pair of inner and outer guide strips time, trouble and expense.

My improved window construction consists essentially of a. window frame and a sash frame, the latter being pivoted to the window frame for swinging movement and in turn slidably receiving the sashes.4 In association with this structural arrangement it is my further'prupose to provide weather strips to maintain a tight fit between the Window and sash frames when the latter is in position with respect to the former. y

With the foregoing and other purposes in view, my invention consists in the Anovel features of coi'istruction,y combination and arrangement of parts as will be hereinafter more fully described7 illustrated in the ac companying drawings and claimed. It is' to be understood, however, that the structure' Speccation of Letters Patent. i patented 11119 6, 1922;

i921.' sensi No. 487,101.

of the essential features of my improvements in apreferred form and. that various changes and desirable additions may be made'in and tothe same within the scope,k and spirt of'my invention as particularly defined in my claims.v l

In the drawings,` wherein like characters of reference denote correspondingparts in the different viewsz- 1 is a front elevation of a window emi on the showing OFFICE. d

villustrated is merely intended as a ldisclosure on vthe line f Fig. 5, a vertical section on the line 5 5 of I Fig. 1; andv Fig. 6, a. transverse section on theline 6 6 of Fig. 5.

Referring now to the 10 designates, generally, the main Iwindow frame, the sameconsisting of the usual sill 11,L vertical side members 12 and yupper transverse connecting member 13. Disposed pair of sidesections which are of duplicate construction, slidably yreceiving "between drawings lin detail,

'Ywithin'this main frameis a sash frame, designated generally at l-and'consistinggof'a them theupper and lower sashes 15and 16, i Y,

respectively. I

Each side section of the sash-l frame con- 17 and 18, respectively, which lextend .the

full length of the frame' and are secured to-' unobstructed to receive the vertical lstiles or A sides of the sashes. Y f Any desired number of connecting pieces 19 maybe providedand arranged asdesired, one of them, however, beinglocated intermediate the-ends of each side section-at a .point preferably midway thereof, av central opening being' provided in each of the latter projects inward from each ofthelvrtical pieccsto receive a stub shaft 20, one of which i incorporated in windows of the type at side members 12 of the main frame. They sash frame, through zthe instrumentality .of the intermediatev metallic connecting pieces 19 and the stub shafts 20, is thus connected to the main frame for swinging movement about a horizontaLa-Xisfand as is apparent, may be swung from its normal closed position illustrated in Figures 1 and '2 to any desired angular relation with. respect to the main frame as intimated by the showing in Fig 3.' By such an arrangement'it is clear .that the sashes may be readily manipulated for. cleaning, repairing or .other purposes, since the saine are at all times slidablewithin the sash frame and in the position of the latter shown in Fig. 3, are removable therefrom asl will 'hereinafter becomev more fully apparent.

Any desired means may be provided to releasably secure the sash. frame in its normal closed position, one preferred means as herein "illustrated consisting of` a spring latch 21 carried by the sash frame, cooperating with a keeper carried .by the main frame.

These elements are desirably located at the top of the window structure on the inside and a cord may therefore depend from the latch lmember whereby the same may tbe conveniently manipulated -to released position. By ypulling` this cord the latch is lreleased fromits 'keeper and the sash frame may then be swung about its axis of rotation to any desired position, but when itis swung to a closed position it is locked by automatic engagement of the latch with its keeper. In this connection it is to be noted that the lower portion of the sash frame swings outward` and the upper' portion swings inward. This is necessitated bythe slope ofthe sill '11, particularly when my improvements are present in common use, the lower ends of the guide strips being beveled to seat against 'thesill and a stop strip 22 preferahly'being secured transversely of the main frame at `the top thereof to serve as an abutment to limit outward swinging movement of the upper portion of the sash frame beyond a predetermined limit.

The inner faces of the vertical stiles or side portions of the respective upperand lower sashes are arranged `in abutting relation, as best shown in the sectional views, 'Figures 4: and 6, while their outer faces are respectively disposedin abutting relation with opposite adjacent faces of the guide strips 17 and 18. Said sashes are thus freely kslidable within the sash frame, but are held against all other movements relative thereto. It is thus apparent that pressure exerted against either sash in the direction of the Vother sash will operate to frictionally 'bind .the latter sash against one or the other of the' guide strips 17 or 18 .and at the same n'time frictionally bind 'the two sashes Vtogether, whereby both of them are rendered incapableof sliding movement. With` this condition present i am enabled to utilize a commercial form of device 23 consistingof a cam operated plunger to exert pressure .against-one of the sashes and thus hold both sashes in any desired slidably adjusted position. 'This device is preferably secured to one of the inner guide strips 17 as best shown in Fig. 4, in such position that the `plunger element thereof operates against the "three-quarter length or substantially so and also provide means whereby sliding movement of either sash imparts corresponding movement to the other sash.

vThe lower substantially one-third portion of the upper sash `and the upper substantially one-third portion of the lower sash are formed of screen sections 2li-and 25,'respectively. When both sashes are in their normal closed position the window is fully closed, since the intermediate portion of fthe upper sash covers the screen section of the lower sash andthe intermediate 'portion of the lower sash covers the screen section of the upper sash. W'hen theflower sash is raised and the upper sash is lowered, however, the screen section ofthe lower sash is moved into position to close the space openedV by the upper sash and the screensection of the up/per sash is moved into position "to close the space opened by thelower sash.

In other words when both sashes are closed reversal of their positions will dispose the screen sections at the top and bottom offthe Window, respectively, and a free :passage or circulation ofair therethrough will be lpermitted, vwhile similarly when both. sashes are open reversal of their positionsfwill effect complete closure ofthe win-dow. Y

The means whereby sliding movement of either sash imparts' correspondingmovement'in a reverse directionV tothe other sash consists essentially in the present instance of a rack member secured'to each sash andv an idler pinion operating therebetween; :De-

sirably duplicate arrangements of thisfkindA are provided at each side of the ywindow to assure smooth and even operation of the sashes, but obviously thedesired results will he .accomplished ,if the arrangement is provided at one side of the window only. i

As best shown in Figures 4 and 6, the adjacent iio faces of the vertical stiles or side portions of the respective sashes are longitudinally recessed and secured in the recess of the upper sash is a rack 26, while secured in the recess of the lower sash is a rack 27. These racks are arranged in facing relationv and are relatively spaced and the pinions 28 which mesh with them are rotatably journaled on the stub shafts 20.

Disposed between the racks above and below the pinions 28, are longitudinally channeled strips 29, the channels of which have rubber or felt 30 therein contacting vwith the inner faces of the side members 12 of the main frame whereby a weather tight fit is produced between said main frame and the sash frame when the latter is closed-see Fig. 6. The channeled strips are secured in position between the racks by suitable fasteners passing through the metallic pieces 19 and as a result form permanent elements of the sash frame side sections.

In association with the structural arrangements recited in the foregoing, means has been provided to eliminate the necessity of sash cords, weights and pulleys to retain the sashes in desired slidably adjusted positions. A lever 31 is pivoted to one of the guide strips, preferably upon one of the securing elements passing through the middle metallic piece 19, and has an end thereof bent to engage between the teeth of' the adjacent pinion 28, in which position it is normally held by a spring 32, thereby preventing rotation of the pinion and consequently locking the sashes against sliding movement. A finger engageable portion of this lever proects beyond the outer face of the guide strip to which it is pivoted so that by pressing the same the other end of the lever is moved out of engagement with the pinion and the latter is then free to rotate. After desired adjustment of the sashes has been effected the lever is released and its spring automatically causes its inner end to engage the pinion, and thus lock the sashes against move* ment.

From the foregoing description taken in connection with the accompanying drawings, it is believed that the construction, opera.- tion and advantages of my improvements will be fully understood, and while I have herein disclosed one specific embodiment of my invention it is apparent that various modifications and changes may be made within the scope and spirit of my invention as defined in the appended claims.

I claim:
